7 Claims. (Cl. l063) This invention relates to a wax-free polishing composition of the aerosol type adapted to be sprayed onto a surface.

It has been customary practice in the past to prepare polishes containing varying amounts of wax in combination with a liquid carrier. In some instances, the wax has been dissolved in a solvent, while in others it has been both dissolved and suspended in a solvent. Where the amount of solvent has been relatively small, the polish has been in the form of a paste with the Wax being both dispersed and dissolved in the liquid. These polishing compositions are applied to wood, metal, lacquer, enamel, varnished surfaces, and other similar surfaces with the intention of giving them a high luster and an attractive, polished surface.

One of the features of this invention is to provide a polishing composition that is wax-free and that is of the aerosol type in which the polishing composition contains a dispersant that is gaseous at ordinary room temperatures and pressures, with the composition being adapted to be retained under superatmospheric pressure in a container so that it may be sprayed over the surface desired by releasing this pressure through a small orifice valve in the customary manner. Dispersants for aerosol products are well known and widely used for many different purposes.

The wax-free polishing composition of this invention includes a combination of an anti-blotching agent, a solvent in which the agent is substantially completely dissolved at ordinary room temperatures, a dispersant that is gaseous at ordinary room temperatures and pressures and which must be confined under pressure when at room temperature, and a minor proportion of a liquid silicone.

The anti-blotching agent is preferably present in an amount of about 0.1-9.0 parts by weight of the composition, with an especially preferred range being about 0.3- parts. The agent is adapted to fill up any cracks in the surface such as often are present in minute form in varnished and finished wood surfaces.

Among the anti-blotching agents that may be used are lauric isopropanolamide, Arochlor 1268 (chlorinated biphenyl containing about 68% chlorine), and Naccanol NRSF, which is sodium dodecylbenzene sulfonate.

The solvent is preferably present in an amount of about 30-50 parts by weight of the composition. This solvent includes Freon l1 (trichloromonofiuoromethane), Freon 113 (trichlorotrifluoroethane), carbon tetrachloride, methylene chloride, chloroform, orthodichlorobenzene, ethylene dichloride, perchloroethylene, trichloro ethylene, benzene, toluene, xylene, coal-tar naphtha, ethyl ether, diisopropyl ether, hexyl ether, amyl acetate, methyl ethyl ketone, Z-ethyl hexanol, cyclohexane, gasoline, mineral seal oil, V. M. and P. naphtha, Stoddards solvent, mineral spirits, etc., and in some cases, acetone, butanol, dioxane, ethanol, heptadecanol, isopropanol, diethyl cellosolve (Carbide and Carbon Company), etc. Thus, the solvent employed should be a liquid, organic material which is a solvent for the silicone employed, and is a .of about 3050 parts by weight.

In some cases, as'with the Freons for example, the solvent can also function as the propellent and vice versa. The solvent should not have a solvent action on the finish which is to be polished, and thus, where. a plain metal surface is to be polished, all of the foregoing solvents will be satisfactory. However, where a nitrocellulose lacquer or varnish, or some alkyd resin finishes, are to be polished, a selection of the solvent to be employed should be rather carefully done, in order that the finish itself may not be deleteriously aifected by the solvent.

The dispersant that is gaseous at ordinary room temperatures and pressures is preferably used in an amount These dispersants include Freon 12 (dichlorodifluoromethane) and Freon 114 (dichlorotetrafluoroethane) as well as many other dispersants that are gaseous at ordinary temperatures and that are well known in the art. These dispersants are preferably blended to produce the desired boiling point so as to avoid dangerous and excessive pressures in the container from which the polishing composition is dispensed.

The silicone materials employed are liquids of substantially linear structure, are substantially non-volatile, and are organopolysiloxanes, preferably essentially polyalkylsiloxanes, and most desirably liquid polydialkylsiloxanes such as dimethyl or diethylpolysiloxanes. A liquid silicone having a minimum of about five centistokes viscosity constitutes the lowest practical operative material which will be employed in most applications. However, a viscosity below about 5,000,000 centistokes constitutes a preferred maximum therefor, and a polydimethylsiloxane having a viscosity range between about 50 to about 10,000 centistokes and a polydiethylsiloxane having a viscosity range between about 5,000 and 100,000 centistokes is the optimum preferred range therefor.

Because of the solubility characteristics of the ingredients, the composition of this invention in its preferred form is a clear product with substantially no sediment. Furthermore, when it is sprayed on furniture or other surface, it wipes off easily to give a good gloss, depth, and clarity.
